Who was/is worst? Rob McKenna or Dino Rossi for Washington Governor?

Republican candidate for Washington Governor, Rob McKenna, is probably smarter than Dino Rossi, and probably more electable. To me that makes him more dangerous. He seems very capable of saying one thing in public, and then doing something different in private, and then getting away with it. Dino Rossi is/was the slimier of the two, but it was so obvious he lost three state-wide elections.
However, there was this picture.
